Target

Function

NAD-dependent 17-beta-hydroxysteroid dehydrogenase with highest activity towards estradiol. Has very low activity towards testosterone. The heteroteramer with CBR4 has NADH-dependent 3-ketoacyl-acyl carrier protein reductase activity. May play a role in biosynthesis of fatty acids in mitochondria.

Tissue specificity

Highly expressed in placenta, liver and pancreas, lower in the skeletal muscle and kidney. Widely expressed.
